Laparoscopic Instruments

    

 Laparoscopic  Tower

Consist of

Ø  High Resolution Monitor-These are flat screen monitors. 

Ø  Light source- A 300-watt xenon light source is usually used. The light is transmitted via flexible, fiber optic bundles connecting the light source to the telescope.

Ø  Viewing Optical System

Ø  Electronic CO2 insufflators-Insuflator (laparoflator) is a device used for introduction of the gas under specified volume and pressure into peritoneal cavity. The CO2 pump should be a high flow insufflation pump with both low flow and high flow settings. Generally, they are capable of delivering high gas flow of 24 L/min, which is limited by the trocar or needle to which it is attached. The insufflation tubing contains a filter that prevents bacterial and viral contamination from possible backflow of surgical smoke, protecting both equipment and health care worker.

Fibro optic cable

This is used to connect light source with optical system. It is necessary to separately check the principles of a precise and accurate treatment with light conductors to avoid damaging thin and sensitive optical glass fibers.

Veress needle

 A Veress needle is used to inflate air into the peritoneal cavity. This needle contains a spring-loaded inner sheath. 

This sheath retracts as the needle is advanced through tissue exposing the needle tip. Once the needle enters the peritoneal cavity, and the majority of theresistance on the needle is released, the inner sheath springs forward.  The inner sheath covers the needle tip and protects the intra-abdominal organs from being injured by the sharp end of the needle.

Trocars

The word trocar is originally French meaning three sided. A trocar is a hollow cylinder with an access mechanism on one side which can be a blade (often three-sided), a plastic lip that is used for dilation, or a radial dilating mechanism. On the external side of the trocar is a valve mechanism which allows instruments to be passed in and out of the patient’s insufflated body cavity while maintaining the insufflated space.  Trocars, also known as ports, usually have a valve to which insufflation tubing can be attached to maintain the insufflation pressure.  Most trocars have an outer sheath (also called a cannula or trocar) and an inner obturator, which allows the access.

Hand Instruments in Laparoscopic Surgery

Hand instruments in laparoscopic surgery serve the same basic functions as open surgical instruments - There are graspers, scissors, needle holders and retractors, but all the instruments are long and narrow, and have small jaws that allow the introduction and use of the instruments through trocars. A unique instrument in Laparoscopic surgery is a "clip applicator"
